frontended doesn't make sense as a word. Fronted has many somewhat applicable definitions including

* provide (something) with a front or facing of a particular type or material. * act as a front or cover for someone or something acting illegally or wishing to conceal something. "he fronted for them in illegal property deals" * stand face to face with; confront.

As a non native speaker I came to the conclusion that in English it is possible to turn any noun into a verb. Not parent but "Frontended" made sense to me.

I'm a native English speaker. Have been for over 50 years. Frontended sounded perfectly natural to me.

Thank you for the clarification.
